This is really just an excuse to flaunt an impressive list of my own by the way, most of it due to my brother. He collects TV shows like I collect toys.
Here goes, in no particular order:
Deep space nine
Star trek: OS
The west wing
Six feet under
Band of brothers (a one-off but it was episodic)
Teachers (a UK show)
ER (an obscure US hospital drama)
Battlestar Galactica (the modern mini-series and possibly the rest)
Most of the above I haven't watched, some of it I never will. Nip/Tuck has my attention at the moment. Can anyone else rack up that many Tv shows in their DVD collections?
